Analysis of Mechanical Sensitivity of MEMS Pressure Diaphragm for Contact Formation

S. Shubham [1], M. Nawaz [1],
[1] Knowles Electronics, Itasca, IL, USA

MEMS Pressure sensors work on the principle of mechanical bending of thin diaphragm under applied load over diaphragm area. The sensitivity of diaphragm is crucial to efficiency of the sensor. It is defined as the increase in deflection of diaphragm as a result of increase in pressure ... Per saperne di più

An Elastohydrodynamic Lubrication Model Considering Surface Roughness and Mixed Friction

J. Moder [1], F. Grün [1],
[1] Chair of Mechanical Engineering, Montanuniversität, Leoben, Austria

Highly loaded lubricated machine elements such as gears or camshafts are an integral part in a wide variety of technical products. Due to higher efficiency requirements these machine elements have to be improved continuously, which leads to the necessity to investigate physical ... Per saperne di più

Statistical Modeling and Contact Analysis of RF MEMS Surface

J. Liu [1], V. B. Chalivendra [1], C. Goldsmith [2], W. Huang [1],
[1] Department of Mechanical Engineering, University of Massachusetts - Dartmouth, Dartmouth, MA, USA
[2] MEMtronics Corporation, Richardson, TX, USA

Radio frequency (RF) micro-electro mechanical system(MEMS) switch works in on/off modes controlled by electrostatic forces. In off mode, rough surfaces of electrodes come into a contact to shunt the RF signal. Surface contact area has been recognized as a key factor in RF MEMS ... Per saperne di più

Simulation of Wear using LiveLink™ for MATLAB®

D. Sutton[1]
[1]National Centre for Advanced Tribology at Southampton, University of Southampton, Southampton, United Kingdom

An incremental wear model has been developed using COMSOL Multiphysics® with MATLAB® to predict the evolution of component geometry as a result of wear. Whilst Archard’s wear law is a well-known empirical model for the prediction of wear volume, the design engineer is interested in ... Per saperne di più

Impact Simulation of Extreme Wind Generated Missiles on Radioactive Waste Storage Facilities

G. Barbella[1]
[1]Sogin SpA, Roma, Italy

The structural design of temporary storage facilities for radioactive waste generally requires the fulfillment of highly severe performance criteria if compared to conventional buildings. This work focuses on the study of the behavior of a steel door subject to the impact of extreme wind ... Per saperne di più
